A Novel Handoff Decision Algorithm in Call Admission Control Strategy to Utilize the Scarce Spectrum in Wireless Mobile Network

Wireless networking is becoming an increasingly important and popular way of providing global information access to users on the move. One of the main challenges for seamless mobility is the availability of simple and robust Channel Allocation algorithm. The radio propagation environment and related hand-off challenges are different in cellular structures. A hand-off algorithm with fixed parameters cannot perform well in different system environments. In this paper, motivated by the facts that the scarce spectrum should be utilized efficiently, a new Dynamic Channel allocation scheme is proposed. Performance of the proposed dynamic channel allocation scheme is compared with existing channel allocation schemes such as fixed channel, static guard channel and Guard Channel with Channel Borrowing.
